More lambs means benefit seniors take measures to improve the lambing rate of ewes

First, do a good job in variety breeding. The fecundity of sheep is inherited, and the fecundity of different breeds is different. There are two births a year or three births in two years, but most breeds produce 3 lambs per fetus, some up to 4 Mel 8 lambs. Therefore, in order to improve fecundity, it is necessary to introduce prolific characteristics in cross improvement, or select prolific variation to fundamentally improve sheep production performance, and at the same time establish and improve breeding registration system and improved breed reproduction system.

Second, select good breed sheep. Excellent breeder sheep are in good condition, energetic, short and round neck, strong physique, rectangular body, deep chest, straight waist, wide and plump buttocks, moderate size and left-right symmetry of testis, far from the base of scrotum, and good semen quality. Sheep with deformities of reproductive organs such as monorchidism and cryptorchidism can not be used for breeding. And breeding ewes, choose large, compact, full muscle, elastic skin, deep chest, straight back, slightly larger rear abdomen, upright limbs, wide spacing, fast growth and development, high meat production rate, more lambs, soft and spherical breasts, good lactation performance, sensitive mind, lively movement, brisk walking, high head, shiny coat color.

Third, optimize the flock structure. Female goats are no more than-8 years old, and the overall structure ratio of ewes, reserve ewes and sheep born in the same year accounts for 47%, 50% and 3% respectively. In addition, in addition to changing the breeding ram once a year to prevent inbreeding, it is also necessary to strengthen the elimination of old sheep, sick sheep, weak sheep, and perennial infertile sheep to ensure that the right-age sheep account for more than 70% of the total number of sheep, so that stable production and high yield can be achieved.

Fourth, strengthen feeding and management. ① spring: the weather is cold and changeable, and it is the lambing season. Ewes bear a heavy burden and have a weak physique. When grazing, they should control their herds, be strong and weak, run less and eat more grass. ② summer: there are many mosquitoes and flies in hot weather, so it is necessary to graze both early and late to create a cool feeding environment for sheep. Try to prolong the time and let the sheep eat more grass. ③ autumn: when grazing, change grasslands frequently and choose places with grass seeds to promote sheep to accumulate more fat and lay the foundation for breeding and overwintering. ④ winter: most ewes in the late pregnancy, coupled with the cold climate, so grazing should be safe, the amount of exercise is appropriate, conditional. Properly replenish high quality hay and concentrate.
